So last night was my first shot at printing on AGFA HDR-C Mammography X-ray film.
Preliminary results are promising!
For the sake of testing, I was projecting negatives to make transparency prints; to better judge the results.
I used Dektol (1:2) at ≈20°C; first for 1', then 1'30", but kept getting uneven development, mottling, etcetera. I increased development time to 3' and got nice & even development.
A strip of film cleared in about 2 minutes in (somewhat old) Kodak Fixer; so I fixed for 4-5 minutes.
Using a 150mm EL-Nikkor and projecting an image that was roughly 6.5" x 8" at f/22 resulted in overexposure with a 2 second exposure. The amazing thing is, my 1st test was 2 minutes (having no idea what speed this stuff was) and this produced a visible image with full tonal information, albeit incredibly dense. So, indeed, the multiple emulsions in the film make for exceptional latitude, though I shudder to think about the printing times onto dichromated gelatin with this.
I'm very curious what kind of results film developer will give. I need to put a strong neutral density filter in the light path to get remotely reasonable exposure times.
The negative I chose printed well on grade 2 previously, and it looked reasonably similar on this film. The blue-base is kinda cool as well.
